Data Feed v2.1
This is a rather minor change to help deal with a few issues we have been having.
The default mode now is to show pending product information if the accepted information is not available. This is the reverse of the previous default. If you don't want any pending information, add pending=no to your URL.
You can no longer updata in any field until the product field is populated. This means that the main product title field must have something in it. We have been getting to many updates of the product category without the name of the product so we have to simply delete the category update because we don't know what that is.
That is all that has changed.
